The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Comparative Molecular Insights into Developmental and Behavioral Toxicity Induced by Octocrylene and Ethylhexyl Salicylate Exposure on Zebrafish

open access: yesIntegrative Zoology, EarlyView.
This study compared the ecological toxicity of organic ultraviolet filters, octocrylene (OC) and ethylhexyl salicylate (EHS), on zebrafish embryos and larvae. EHS exhibited higher acute toxicity, causing increased mortality, hypoactive behavior at 50 mg/L, and disruptions in lipid homeostasis, while OC primarily affected hypoxia response and ...

(Not) Covering Climate Risks: A Multimodal News Framing Analysis of Soil Health Reporting in the UK Press

open access: yesThe Geographical Journal, EarlyView.
Short Abstract Risks to soil health from increased flooding and drought due to climate change are a priority risk area for the UK government, but our analysis of two years of UK newspaper coverage on this issue reveals very little attention to it. Our multimodal framing analysis shows that news reports are largely devoid of addressing the root causes ...

Free‐living Black‐tailed Godwits maintain constant intake rates across varying grassland habitat conditions by adjusting their foraging behaviour

open access: yesIbis, EarlyView.
Free‐living birds need to acquire enough food to fulfil their energetic needs, which may require more effort in habitats with less favourable conditions. Therefore, to maintain their necessary energy intake, birds need to adjust their foraging behaviour in response to varying habitat conditions.
